Maverick will lie like this all day, if you let him. With his feet up like that, it’s actually called Bronco’ing. This is a position Senegal Parrots are known to love. They will often flip themselves onto their backs just to lay that way. It can be a defensive posture, though, as this puts the talons out for striking. (In this case, though, he’s just loving life.)
